A self-study of teaching teachers using Epistemic Insight
Epistemic Insight (EI), defined as knowledge about knowledge (Billingsley et al, 2018) examines how distinctive forms of disciplinary knowledge can interact providing solutions to real world problems Utilising an interdisciplinary approach EI seeks to critically examine the current subject compartmentalization in the school curriculum, which leads to a siloed nature of school education within the UK and as a consequence a siloed education for preservice teachers (Billingsley et al, 2024). In introducing EI to preservice science teachers, we have identified the need to examine our practice as science teacher educators by refining views on the nature of science. Adopting EI within our teaching challenged us as teacher educators to re-examine the structure of our programmes. By adopting EIâs framework of examining questions with an interdisciplinary focus, we identified that our views on the foundations of scientific knowledge are not aligned despite the experience of the authors in science teacher education. This finding is illuminating given recent neoliberal shifts to standardise teacher education in England as implemented through the market review of ITT that is currently scrutinising curriculum providers curriculum materials (Mutton & Burn, 2024).
Thus, in this paper, we seek to problematise the nature of teaching teachers about EI. Berry (2008) reminds us that efforts to address problems using self-study do not lead to simple solutions. Introducing a self-study model that draws on the idea of the tension between the actions and intent of teaching about EI, we examine our practice as teacher educators critically to explore the differences in understanding the nature of science. Our self-study is framed by analysing podcasts that discussed the dissemination of EI across distinct initial teacher education courses. Triangulating this with lesson studies enabled us to examine how our views of the nature science manifest in teaching practices and illuminate the tension between actions and intent. This paper, therefore, examines how we use our engagement with EI as a research -informed pedagogic framework to prompt pedagogic practice as science teacher educators. We argue adopting EI as a pedagogic framework not only supports preservice teachers to critically examine the compartmentalisation of Education, but further promotes deeper epistemically insightful understanding of how individual disciplines are distinctive. This in turn refines the practice of teachers and teacher educators alike
Transforming teacher education - introducing ITE students to Epistemic Insight: a workshop
Epistemic insight is a curriculum and innovation research initiative transforming teacher programmes across England. Epistemic Insight (EI) means ' knowledge about knowledge' and in particular how knowledge is constructed within disciplines and how it interacts across them. This involves using techniques to examine disciplinary boundaries and encouraging students to think beyond their own subject. The epistemic insight initiative has a consortium of ITE providers who have worked with their students exploring real-world problems in an interdisciplinary way using epistemic insight tools and strategies. This enabled secondary ITE students of various specialisms to collaborate across disciplines enriching their learning and teaching practice. This workshop will present the work completed at St Maryâs University, The University of Leicester and Birmingham University. The lessons learnt and future directions will be studied. The workshop will give delegates an opportunity to explore resources used and discuss with consortium members how and why you may want to introduce you students to EI.

Front gardens to car parks: changes in garden permeability and effects on flood regulation
This study addresses the consequences of widespread conversion of permeable front gardens to hard standing car parking surfaces, and the potential consequences in high risk urban flooding hotspots, in the city of Southampton. The last two decades has seen a trend for domestic front gardens in urban areas to be converted for parking, driven by the lack of space and increased car ownership. Despite media and political attention, the effects of this change are unknown, but increased and more intense rainfall, potentially linked to climate change, could generate negative consequences as runoff from impermeable surfaces increases. Information is limited on garden permeability change, despite the consequences for ecosystem services, especially flood regulation. We focused on eight flooding hotspots identified by the local council as part of a wider urban flooding policy response. Aerial photographs from 1991, 2004 and 2011 were used to estimate changes in surface cover and to analyse permeability change within a digital surfacemodel in a GIS environment. The 1, 30 and 100 year required attenuation storage volumes were estimated, which are the temporary storage required to reduce the peak flow rate given surface permeability.Within our study areas, impermeable cover in domestic front gardens increased by 22.47% over the 20-year study period (1991â2011) and required attenuation storage volumes increased by 26.23% on average. These increases suggest that a consequence of the conversion of gardens to parking areas will be a potential increase in flooding frequency and severity â a situation which is likely to occur in urban locations worldwide

Foundation and empire : a critique of Hardt and Negri
In this article, Thompson complements recent critiques of Hardt and Negri's Empire (see Finn Bowring in Capital and Class, no. 83) using the tools of labour process theory to critique the political economy of Empire, and to note its unfortunate similarities to conventional theories of the knowledge economy
Giving Miss Marple a makeover : graduate recruitment, systems failure and the Scottish voluntary sector
The voluntary sector in Scotland, as across the globe, is becoming increasingly business like. Resultantly, there is an increasing demand for graduates to work in business and support functions. In Scotland, however, despite an oversupply of graduates in the labor market, the voluntary sector reports skills shortages for graduate-level positions; a leadership deficit was also reported in countries such as the United States. Through exploratory, mainly qualitative, case study and stakeholder research, this article proposes that one reason for this mismatch between the supply of and demand for graduates is a systems failure within the sector. Many graduates and university students remain unaware of potentially suitable paid job opportunities, in part because of the sector's voluntary label. To rectify this systems failure, thought needs to be given to the sector's nomenclature and the manner in which voluntary sector organizations attract graduate recruits, for example, through levering value congruence in potential recruits
The New âHidden Abodeâ: Reflections on Value and Labour in the New Economy
In a pivotal section of Capital, volume 1, Marx (1976: 279) notes that, in order to understand the capitalist production of value, we must descend into the âhidden abode of productionâ: the site of the labour process conducted within an employment relationship. In this paper we argue that by remaining wedded to an analysis of labour that is confined to the employment relationship, Labour Process Theory (LPT) has missed a fundamental shift in the location of value production in contemporary capitalism. We examine this shift through the work of Autonomist Marxists like Hardt and Negri, Lazaratto and Arvidsson, who offer theoretical leverage to prize open a new âhidden abodeâ outside employment, for example in the âproduction of organizationâ and in consumption. Although they can open up this new âhidden abodeâ, without LPT's fine-grained analysis of control/resistance, indeterminacy and structured antagonism, these theorists risk succumbing to empirically naive claims about the ânew economyâ. Through developing an expanded conception of a ânew hidden abodeâ of production, the paper demarcates an analytical space in which both LPT and Autonomist Marxism can expand and develop their understanding of labour and value production in today's economy. </jats:p
Superhumps in Cataclysmic Binaries. XXV. q_crit, epsilon(q), and Mass-Radius
We report on successes and failures in searching for positive superhumps in
cataclysmic variables, and show the superhumping fraction as a function of
orbital period. Basically, all short-period systems do, all long-period systems
don't, and a 50% success rate is found at P_orb=3.1+-0.2 hr. We can use this to
measure the critical mass ratio for the creation of superhumps. With a
mass-radius relation appropriate for cataclysmic variables, and an assumed mean
white-dwarf mass of 0.75 M_sol, we find a mass ratio q_crit=0.35+-0.02.
We also report superhump studies of several stars of independently known mass
ratio: OU Virginis, XZ Eridani, UU Aquarii, and KV UMa (= XTE J1118+480). The
latter two are of special interest, because they represent the most extreme
mass ratios for which accurate superhump measurements have been made. We use
these to improve the epsilon(q) calibration, by which we can infer the elusive
q from the easy-to-measure epsilon (the fractional period excess of P_superhump
over P_orb). This relation allows mass and radius estimates for the secondary
star in any CV showing superhumps. The consequent mass-radius law shows an
apparent discontinuity in radius near 0.2 M_sol, as predicted by the disrupted
magnetic braking model for the 2.1-2.7 hour period gap. This is effectively the
"empirical main sequence" for CV secondaries.Comment: PDF, 45 pages, 9 tables, 12 figures; accepted, in press, to appear

Validation of a chloroquine-induced cell death mechanism for clinical use against malaria
An alternative antimalarial pathway of an âoutdatedâ drug, chloroquine (CQ), may facilitate its return to the shrinking list of effective antimalarials. Conventionally, CQ is believed to interfere with hemozoin formation at nanomolar concentrations, but resistant parasites are able to efflux this drug from the digestive vacuole (DV). However, we show that the DV membrane of both resistant and sensitive laboratory and field parasites is compromised after exposure to micromolar concentrations of CQ, leading to an extrusion of DV proteases. Furthermore, only a short period of exposure is required to compromise the viability of late-stage parasites. To study the feasibility of this strategy, mice malaria models were used to demonstrate that high doses of CQ also triggered DV permeabilization in vivo and reduced reinvasion efficiency. We suggest that a time-release oral formulation of CQ may sustain elevated blood CQ levels sufficiently to clear even CQ-resistant parasites
